Horse owner&#39;s and farrier&#39;s stand

ABSTRACT

An adjustable horse owner&#39;s and farrier&#39;s stand includes a base having a large generally flat base and an upright portion upending from the base, and a hoof platform adjustably locked in the base. The hoof platform height may be adjusted continuously rather than incrementally for precise and accurate positioning of a hoof. One hoof platform includes a diverging U-shaped cradle, with a firm but cushioning, shock-absorbing material on its top side for elevating the hoof and absorbing the concussion of nailing and hoof maintenance. Preferably, the firm but cushioning material is a flexible strap slung across the cradle to form a hoof-receiving sling spaced above the surface of the cradle. Interchangeable hoof platforms may be provided, such as an alternative platform with a flat surface to receive the bottom of a hoof. The preferably plastic base, and the continuous adjustability of the height of the hoof platform, provide a quiet, substantially non-metallic, and non-intimidating stand that does not frighten most horses.

[0001] This application is a continuation-in-part of, and claimspriority from, U.S. patent application Ser. No. 10/008,681, filed Dec.4, 2001, entitled “Horse Owner's and Farrier's Stand”, issued as U.S.Pat. No. 6,640,905, which is a continuation-in-part of U.S. patentapplication Ser. No. 09/454,797, filed on Dec. 3, 1999, entitled “HorseOwner's and Farrier's Stand”, issued as U.S. Pat. No. 6,325,154 on Dec.4, 2001, the disclosure of which is incorporated herein by thisreference.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] This invention generally relates to tools for farriers,veterinarians and horse owners. More particularly, this inventionrelates to a stand for supporting a horse's hoof or foot for horseshoeremoval, hoof trimming, horseshoe fitting, horseshoe installation andhoof maintenance.

[0004] 2. Related Art

[0005] Most farriers physically support the horse's leg during shoeingoperations by holding the horse's leg between their own legs, with thehorse leg coming through the farrier's legs from the farrier's backside.This is a precarious, sometimes dangerous position and always aphysically-demanding position. First, the farrier must remove the oldhorseshoe. Then the hoof must be trimmed and filed. Next, the new shoemust be fitted to the hoof profile and nailed in place. Finally, thenails are clinched and the anterior profile of the hoof is filed andshaped. All of these operations are best performed with the hoofsupported at an elevation above ground level.

[0006] U.S. Pat. No. 4,167,216 for a Multiple Stand To Aid ShoeingHorses teaches a two-position tripod-type stand having a pair ofalternating upright members disposed at a right angle with respect toone another. A pair of opposing legs are connected to the vertex jointof the uprights, each at a slightly obtuse angle with respect to bothuprights. In one position, one upright extends vertically upward whilethe second upright acts as the third leg of the tripod. In the secondposition, the second upright extends vertically upward while the firstupright acts as the third leg of the tripod. A hard hoof cradle isattached to the distal end of one of the uprights and a flat plate isattached to the distal end of the other upright. The cradle holds thehoof in an elevated generally horizontal position to provide access tothe bottom of the hoof, while the flat plate provides an elevatedplatform to support the bottom of the hoof to provide convenient accessto the anterior of the hoof. An optional upright with an anvilattachment can be removably substituted for either of the other twouprights.

[0007] U.S. Pat. No. 4,167,216 device has some disadvantages. First, thelength of the uprights are not adjustable to accommodate the necessarydifference in working height between front and back hooves of a singlehorse, nor to accommodate different-sized horses. Second, the hoofcradle construction does not provide any concussion absorption and isprone to the hoof dislodging from the cradle. Thirdly, the legs andhorizontally extending upright (effectively a leg) pose a hazard both tothe farrier and to the horse.

[0008] Blackburn (U.S. Pat. No. 89,379) discloses a rest for shoeinghorses with a thick base and a hinged, v-shaped member upon which thehorse hoof rests. The arms of the v-shaped member extend verticallyupward, and one of the arms is hinged to pivot to the side when theweight of the hoof is placed on the v-shaped member. The Blackburndevice includes an incremental ratchet adjustment to raise and lower thev-shaped member relative to the base. The inventor believes that priorart devices, such as the Blackburn device, would tend to haveundesirable effects on a horse, including metallic sounds during heightadjustment, of metal against metal, that would upset/frighten theanimal. Because horses are usually nervous, easily-frightened animalsthat respond instinctually to noises and unfamiliar or uncomfortablemovements according to the well-known “fear-flight” behavior. Further,the inventor believes that prior art devices, which include incrementalraising or lowering a metal upright inside a metal receiver tube using aratchet system, would tend to cause uneven and jerky motion and metallicsounds created by relative movement and contact of the metal upright andreceiver tube. The inventor believes that pivoting/flexing arms or othermoving parts would upset/frightened the animal, especially if thepivoting/flexing occurs in response to the weight of the animal's footand if it causes the stand to “clamp” the foot/hoof.

[0009] What is needed is an adjustable-height, safer stand that moresecurely holds the hoof in the horizontal position. What is still neededis a stand that is less intimidating to both horses and users. What isneeded is a light-weight and convenient stand that is comfortable andquiet, for non-stressful work with a horse's hoof and/or foot.

SUMMARY OF THE INVENTION

[0010] The invention comprises a farriers' and horse owners' stand(hereafter also called “horse owner's stand” or “stand”) that ispreferably substantially plastic and, therefore, is quiet andlightweight. The stand includes a broad, flat base and a hoof supportsystem upending from the base. The hoof support system is adjustable inheight and includes a hoof-receiving platform at its top end. Severalhoof-receiving platforms may be provided that are removable andinterchangeable with each other. The preferred height-adjustment iscontinuous rather than incremental, and the height-adjustment meanspreferably is substantially silent and smooth.

[0011] The broad, flat base is preferably nearly as wide in diameter asthe upending hoof support is tall, that is, the flat base diameterpreferably is about 75% to 130% of the height of the stand, dependingmainly on how high the hoof support is adjusted. Buttresses or otherreinforcements preferably extend from the upending portion of the standhoof to the flat base to strengthen the stand overall withoutunnecessarily increasing the total weight. The flat base is preferablyround and preferably tapers from a thicker center area to be thinnernear its outer edge, to provide a top surface that slants downwardtoward the outside. This slanting top surface and thin outer perimeterallow a user to stand on the base with at least one foot and preferablyboth feet to anchor the invented stand as it is used. Further, the standmay include holders or fasteners for holding tools and/or replacementhoof platforms for storage and easy access.

[0012] One embodiment of the invention includes a polyethylene baseformed having a large generally flat base and a narrow,truncated-conical upright receiving portion centrally protruding fromthe base. A hoof platform is configured to be slidably held within theupright receiving portion and a lock is provided for securing the hoofplatform within the upright holder receiving portion at a selectedheight. A first hoof platform includes a diverging U-shaped cradleattached to its distal end. A flexible strap, such as a nylon webbing,is slung across the cradle and attached to the opposing ends of thecradle to form a hoof-receiving sling. The cradle and strap areconfigured to securely hold the hoof and absorb concussion associatedwith nailing and hoof maintenance, and, in this respect, thehoof-receiving sling may be considered one type of firm yet cushioningstructure. A second hoof platform simply provides a generally flatsurface to receive the bottom of a hoof at an elevated position abovethe ground for anterior hoof work. Both hoof platforms are sized andshaped to be closely and slidably received within the upright receivingportion, and to be fixed along their respective lengths relative to theupright receiving portion to adjust the working height by the adjustablelock.

[0013] The combination of the polyethylene base and the preferredflexible-strap cradle provide a cushioning and quiet device forminimizing stress to the horse, while also providing a firm platformthat gives the horse owner or farrier a sure, steady and safe workplatform on which the hoof will not wobble or significantly shift duringthe work. The generally flat polyethylene base provides a safe andstable support for the stand and diminishes the chance of either thefarrier or the horse from being injured by tripping over, or steppingon, a protruding leg.

[0014] Additionally, the broad plastic base provides for concussionabsorption and distribution. The base is formed with a rounded perimeteredge, and from a material which is much softer than the metal used inprior art stands. Additionally, the edges of the cradle are preferablyrounded to reduce the chance of injury, as well as the wear on theflexible strap. The combination of the flexible strap and the plastic orsimilar material base, provide a hoof support system which is has beenfound to be much more acceptable to all horses tested.

[0015] Additional advantages and novel features of the invention will beset forth in part in the description that follows, and in part willbecome apparent to those skilled in the art upon examination of thefollowing or may be learned by practice of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Referring now to the Figures, a horse owner's stand according toone embodiment of the invention is shown in detail and generallydesignated as stand 10 herein. The horse owner's stand includes a broad,generally flat base with a hoof support system upending from thegenerally flat base, wherein the hoof support system preferably isadjustable in height and includes interchangeable platforms fordifferent positioning and handling of the horse's hoof and foot.

[0024] In the preferred embodiment horse owner's stand 10 shown in theFigures, the broad, generally flat base and a generally vertical uprightreceiving portion are combined in a single, preferably molded plasticbase unit, called polyethylene base unit 11. Base unit 11 has largegenerally flat base 12 and a narrow, truncated-conical upright receivingportion 13 centrally upending from flat base 12. Into the uprightreceiving portion 13 is slidably inserted a hoof platform 14, whichincludes post 15 at its lower end and an upper end adapted forcomfortable and secure handling of the hoof. Additionally, post 15 isconfigured to be closely but slidably held within the interior bore 16of upright receiving portion 13. While post 15 may be made of variousmaterials, post 15 is preferably manufactured of metal tubing having anoutside diameter slightly less than the inside diameter of bore16/sleeve 16′. While a circular cross-sectional shape is not necessarilycritical to this aspect of the invention, it is critical that post 15 beslidably received within bore 16, and that post 15 may be locked inplace at different elevations in the bore 16, preferably with thedifferent elevations translating to about 8-10 inches of heightadjustment. Although other height adjustment ranges may be incorporatedinto the stand design, 8-9 inches is a reasonable range that fits mostuser's and most horses comfortably.

[0025] Thus, one may see that the hoof support system of the preferredembodiment includes cooperating upright receiving portion 13 and hoofplatform 14, wherein hoof platform 14 that may be raised and lowered inreceiving portion 13 to adjust the overall height of the stand 10. Byadjusting the overall height of the stand 10, the user sets the exactelevation of the top surface of the hoof platform relative to the bottomsurface of the base 12, which, in effect, adjusts the elevation of thetop surface of the hoof platform relative to the ground or floor uponwhich the stand rests.

[0026] An adjustable lock 17 cooperates between upright receivingportion 13 and hoof platform 14 to secure post 15 within the base unit11 at a selected height. In the preferred embodiment, adjustable lock 17includes a set-screw style threaded shaft 27′ with user-accessible knob27, which may be turned to lock the post 15 in place at a particularheight in the bore 16. Shaft 27′ extends through the wall of uprightreceiving portion 13, threadably engaging the wall surface of hole 28,and into the bore 16 to frictionally engage the post 15. The knob 27 issized large enough to comfortably fit in a user's palm, so the user maycomfortably apply enough force when turning in the lock 17 to secure thepost against slippage. The outer surface 115 of post 15 should be asmooth cylindrical surface, so that engagement of the shaft 27′ on theouter surface may be done at any radial and axial position on the post.By “smooth” is meant that there are no significant ridges or grooves orother ledges that would interfere with continuous adjustment of the postin the base unit.

[0027] It should be noted that, while other lock mechanisms may beimplemented, such as a tightening collet, pin and through hole, ratchetand pawl, or others, the preferred lock mechanism should allowcontinuous rather than incremental adjustment of height, so thatextremely small adjustments may be made smoothly. Ratchet mechanisms orpin-through-hole mechanisms are definitely less preferred, because theyare inherently incremental. Such incremental adjustments do not providethe very minute height adjustments that are important when working withthe stand 10 and the horse's hoof/foot. Also, as discussed below,incremental adjustments typically have the added problem of creating ajerky or noisy adjustment, which, when made during the work on thehoof/foot as it often the case, can scare or stress the animal.

[0028] Hoof platform 14 has at its upper distal end a sling cradle unit22, made from diverging “U” shaped cradle 18 plus a flexible strap 21that extends across the cradle 18 to form the upper surface of thecradle unit 22. Cradle 18 is made from metal bent to form a central webportion 19 and two outwardly and upwardly extending arms 20 thatpreferably rigidly and non-pivotally extend from the web portion 19, andwherein there are no hinges or moving joints in the cradle 18. The topends of arms 20 preferably have rounded corners and/or rounded edges toreduce the chance of injury and wear on strap 21.

[0029] Flexible strap 21, preferably manufactured of a nylon strapmaterial, is slung across cradle and attached to the opposing ends ofarms 20, creating a space 121 between the strap 21 and the web portion19. Here, strap 21 is attached to the outside upper surfaces of arms 20using a pair of metal strap plates 23 and cooperating bolts and nuts 24.Strap plates 23 extend across substantially the entire width of thestrap 21, to provide even and firm pressure across the strap 21 at bothends of the strap 21, so that there is little chance of the strappulling out from under the plates and off of the cradle 18.Advantageously, the bolts are countersunk in upwardly extending arms 20.This configuration ensures that the heads of the bolts are shielded, bystrap 21, from coming into contact with the hoof. Cradle 14 and strap 21are sized to create a flexible curved surface to contact a substantialportion of the curved anterior surface of a hoof to securely hold thehoof and absorb concussion associated with nailing and hoof maintenance.By providing a cradle unit 22 that does not flex, pivot, or otherwisemove, except for the flexing of the strap 21, the user may be confidentof secure placement of the horse's hoof and the horse does notexperience unexpected or sudden movement or shifting of its hoof/foot.

[0030] Hoof platform 14 is removable from the base unit 11, so thatalternative hoof platforms may be installed. An example of analternative hoof platform 25 (“second platform 25”) is shown in FIG. 8.Second platform 25 is slidably and lockably received by uprightreceiving portion 13 in place of first hoof platform 14. Second hoofplatform 25 does not have cradle 18, but instead an upper flat surface26. Upper flat surface 26 provides a flat surface to receive the bottomof a hoof at an elevated position above the ground for anterior hoofwork.

[0031] Advantageously, the base unit 11 is approximately twelve andone-half inches high, post 15 is approximately ten inches long andcradle 18 is approximately 2½-3 inches high. Additionally, web 19 isapproximately 3-3½ inches long while arms 20 are approximately 2½-3inches long. Arms 20 preferably extend upward at opposing angles ofapproximately sixty degrees with respect to horizontal, as illustratedby angle “A” in FIG. 3, and preferably angle A is in the range of 50-70degrees. Strap 21 is approximately 8-10 inches long with approximately1½ inch overlaps extending down the outside of each arm 20, leavingapproximately 5-7 inches to form sling 22. Strap 21 and cradle 18 areeach approximately three inches wide (measured transverse to the longdimension of the cradle). The top surface of second hoof platform 25 maybe various dimensions, but preferably it is just slightly larger thanthe diameter of the post 15. Preferably, a rubber or other non-metal cap125 is placed on the post, wherein the rubber or non-metal material isfirm but not hard, so that there is a slight resilience or cushioningeffect but not a spongy or unstable effect when the hoof is placed on ormoves on the cap 125. As an alternative to the flexible strap, a cushionmaterial may be placed in the cradle 18 but the cushion should be a firmcushion that supports and controls the hoof during work on the hoof.

[0032] When the lock is loosened, the platforms 14, 25 may slide down toa maximum extent into the receiving portion 13 for compact carrying andhandling. While these dimensions accommodate most horses quite well, itshould be noted that at least the cradle and sling dimensions can bemodified to accommodate different sized horses, such as draft horses orminiature horses.

[0033] The stand 10 preferably includes one or more holders for toolsand/or optional hoof platforms. In the preferred embodiment, a magneticholder 50 is supplied on the outside surface of the receiving portion13. This is excellent for holding metal tools, such as files. A Velcro™strap loop-style holder 52 is also provided, for being strapped around atool or, more preferably, around the post of an alternative hoofplatform. Because the receiving portion 13 is preferably substantiallyplastic, the tool being held on the portion 13 will not “clank” againstthe outer surface of portion 13, so the horse is not frightened bymovement of such accessories.

[0034] Buttresses 55 are preferably included on the base unit 11 betweenthe receiving portion 13 and the flat base 12. These serve to strengthenthe stand 10 without adding undue weight. The flat base 12 is called“flat” but most preferably slants downward to a thin, rounded outerperimeter edge 56 from a slightly thicker center region 58. At its outerperimeter edge 56, the base 12 is preferably less than 1 inch thick.This top slanted base surface 60 is an excellent surface for the user tostand upon while working with the horse, thus, stabilizing the stand 10and preventing it from tipping over or shifting in position. The userplaces the stand 10 between his legs and stands on the base 12, whichprovides for the horse a “feel” similar to what the horse is used toduring hoof maintenance, but with more security and sureness and withless movement.

[0035] The preferred embodiment provides positive answers to manyobjects that desired in a stand for horses. Because the base 12 is allor substantially plastic (preferably polyethylene), the base 12 does notmake significant noise against the floor/ground. Because the stand 10has a smooth, non-ratchet adjustment system, it does not makesignificant noise during use and adjustment. Rather than the uneven andjerky movement of ratcheted metal pieces, the preferred stand 10 has apost moving smoothly in a base unit in a non-jerky manner. Also, thecontinuous adjustment afforded by the set-screw style adjustment systemis superior to incremental adjustments, for effectiveness andconvenience and accuracy when working with the horse.

[0036] Further, the preferred rigid U-shaped cradle withslightly-diverging arms provides a proper shape and “feel” for thehorse. The cradle 18 does not move when the horse's foot/hoof is restedin it, rather, the strap 21 on the cradle slightly and smoothly andgently deforms to cushion the foot/hoof. There is no clamping feelinggiven to the foot and no noise or sensation of significant movement. Thecombined effect of the plastic base and the set-screw style system, andthe rigid U-shaped cradle, both produce a surprisingly quiet and calmingdevice for working with a horse. The preferred substantially plasticstand does not produce a metallic sound when it is brought up to theanimal, when it is moved on a hard surface, or when it is adjusted orused. The bore 16 in the base unit may be plastic or may be lined with asleeve 16′, as shown in FIGS. 4 and 5. The sleeve 16′ may be plastic, sothat the height adjustment involves metal to plastic contact of the postin the bore, not metal to metal movement/contact. Alternatively, thesleeve 16′ may be metal and the wall surface of hole 28 may be metal,increasing durability and reliability of the height adjustment system.Whether the bore wall is plastic or metal, the horse is hardly aware ofthe non-intimidating device during its use and adjustment and is notfrightened by sound or movement. This is a surprising difference inhorse behavior compared to horse behavior with prior art metal stands.Further, the invented stand 10 is lightweight and easy and safe tocarry, as it preferably weights less than 8 pounds and has no sharpedges.
